School of Electrical Engineering and Computer Sciences (SEECS) is a constituent college of National University of Sciences and Technology (NUST), Pakistan - SEECS was formerly known as NIIT (NUST Institute of Information Technology). Since SEECS has been an important collaborator with SLAC, CERN and Caltech, we prepared a case study presenting an overview of the issues faced by SEECS in particular and Pakistan in general.
The PingER project maintains six (7) monitoring nodes in Pakistan, measuring the performance of sites listed in the table - monitored nodes - below. These monitoring sites are deployed in Islamabad at the following locations:
